WELT MACHINE.

SPECIFICATION forming part of Letters Patent No. 427,610, dated May 13, 1890. Application filed December 2, 1889. Serial No. 332,329. (No model.) Patented in England February 6, 1889, No. 2,156.

To all whom it may concern.-

Be it known that I, HENRY COOPER PRETTY, a subject of the Queen of England, residing at Leicester, in England, have invented certain new and useful Improvements in Machines for the Preparation of elts for Use in the Manufacture of Boots or Shoes and in Apparatus Therefor, (for which I have applied for Letters Patent of Great Britain, No. 2,156, dated February 6, 1889,) of which the following is a specification.

The object of this invention is the preparation of welts or rands for use in the manufacture of boots and shoes and the provision of an apparatus for skiving or beveling, channeling or grooving, and trimming the edge of the welt at one operation.

The particular construction of the apparatus and the operation will be understood from the following description, with reference to the accompanying drawings, in which-- Figure 1 is a perspective View showing the top side of the apparatus. Fig. 2 is another perspective View showing the mechanism underneath the bed of the apparatus. Fig. 3 is a back elevation, and Figs. 4, 5, 6, and '7 are details.

The whole of the parts are secured or connected to a bed-plate A, which may be loosely fastened to a table or other support by a screw A, to enable the bed plate to be raised on the hinge B, as shown in Fig. 2, when it is desired to adjust or otherwise attend to the underneath mechanism. The opposite end of the bed is slotted at G and bears against a screw C, fixed in the table to keep the apparatus rigid and in position during the operation of preparing the welts, as described, and to admit of the bed-plate A being turned on the screw A to raise it on the hinge B, as before mentioned. The central part of the bedplate is raised or elevated, as shown. Fixed to the bed-plate by screws D D is the skiving or beveling knife D, (shown detached in Fig. 4,) having its bevcling-edge at D and raised in its central portion to admit of the rand or welt passing thereunder, and also that the edge trimmer E (shown detached in Fig. 5) and grooving or channeling knife or tool F (shown detached in Fig. 7) may be fixed underneath.

The extent to which the central portion of the beveling or skiving knife D is raised above the bed of the apparatus may be varied in additional or different knives according to the thickness of the welt to be operated upon. The knife D, being rigidly fixed to the bedplate, will remove or level any uneven places on the upper surface of the welt that may come into contact with its under edge D, Fig. 3, while passing underneath the knife D.

The knife E, Fig. 5, for trimming the edge of the welt, has a cutting-edge at E, and is adjustable in relation to the beveling-knife D by means of the screws E E passing through the slots E and into the bed-plate A. The edge-trimmer E may be fixed nearer to or far ther from the cutting-edge D of the skiving or beveling knife D, according as it is desired to treat narrow or wide welts. The side E of the edge-trimmer E acts as a guide to the welt while passing the knives.

G. (shown detached in Fig. 6) is a guard secured to one side or edge of the bed-plate A by means of a screw G, and is adjustable in relation to the cutting-edge D of the beveling or skiving knife D by means of a slot G The amount of leather removed from the welt by the beveling-knife D varies according to the relation that the guard G bears to the cutting edge D of the former.

Formed integrally with or attached to the back edge of the bed-plate is an angle-plate H, on the upper face of which, and capable of a backward and forward movement through the medium of slots H is a plate J, carrying at its foremost end a flanged guide-roller K, adapted to rotate on the screw or pivot K to facilitate or accelerate the introduction of the welt to the operating knives as the edge of the welt moves into contact with the periphery of the roller K.

The plate J is elastically fixed to the angle-plate H by the screwed spring-encircled rod J. The guide-roller K can be adjusted in relation to the operating-knives for various widths of welts by means of the set-screw J whose inner end is in contact with the end of the angle plate I-I.

The channeling or grooving tool F has its lower end rigidly fixed in a base-plate L by a set-screw L and projects upwardly through a slot in the bed-plate A. It is adjustable laterally by means of the slot L and screw L Fig. 2, in the base-plate L. The distance it may be moved in either direction may be regulated according as the groove or channel is to be nearer to or farther from the edge of the welt. The upper end of the channeling or grooving tool F is formed with a cuttingeye F, which projects above the bed-plate more or less, according as the groove or channel in the welt is required to be deeper or shallower. The extent to which it may be adjusted for this purpose is determined by the set-screw L whose upper end is in contact with the under side of the bed-plate, and which on being tightened or released lowers or raises the cutting-eye of the grooving-tool in relation to the bed-plate to a corresponding extent.

Instead of constructing the apparatus, as hereinbefore described, for simultaneously skiving, channeling, and trimming the welt or rand, it may be constructed so that any two of these operations may be effected at the same time.

I claim- 1. In a machine for treatin" shoe Welts or rands, the combination, with the base, of the knife D, secured rigidly thereon and having the horizontal and inclined cutting-surfaces for leveling and beveling the welt, and the edge-trimmer E, adjustably secured on said base opposite the inclined cutter of the knife D, whereby the welt or rand is leveled, "beveled, and the edge trimmed at one operation, substantially as described.

2. In a machine for treating shoe welts or rands, the combination, with the base, knife D,rigidly secured thereon, and edge-trimmer E, adjustably secured thereon and provided with a guide, of the grooving-cutter F, adj ustably mounted on said base, substantially as described.

3. In a machine for treating shoe welts or rands, the combination, with the base and knife D, rigidly secured thereon, of the guide HENRY COOPER PRETTY.
